PICK.

Specification of Letters Patent. Patented; NOV. 30, 1915.

Application filed February 15, 1915. Serial No. 8,296.

To all whom it may concern Be it known that I, ELMER E. RHO'ADS, acitizen of the United States, residing at Lockman, in the county ofMonroe and State of Iowa, have invented certain new and usefulImprovements in Picks, ofwhich the following is a specification.

The invention provides novel means for detachably connecting a tool toits handle in a manner to admit of any play in the joint being readilytaken up or the tool be ing quickly removed from the handle whenoccasion requires and also to secure a firm and rigid connection'wherebythe tool is enabled to withstand hard usage without becoming loose. 7

A further purpose of the invention is the provision of a joint betweenthe tool and I handle embodying elements which are mutually bracing withthe result that the strain is equalized on all the parts, the jointbeing of such formation as to admit of any one of the cooperatingelements being easily and readily replaced in the event of'fracture orother cause rendering the joint insecure and repairs. essential.

With these and other objects in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly claimed.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention as claimed may be resorted to when desired.

Referring to the drawings,Figure 1 is a side view of the inventionapplied to a miners pick. Fig. 2 is a sectional view showing moreclearly the relative arrangement of the cooperating elements. Fig. 3 isa detail perspective view of the pick head. Fig. 4: is a detailperspective view of the socket. Fig. 5 is a detail perspective view ofthe connecting bolt. Fig. 6 is a modification showing the head providedwith removable L-shaped studs.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

shaped studs may form a part of the tool or may be applied thereto inany manner to admit of ready" replacement, should occa s on require.Openings 6 are formed in the side of the tool or pick head provided withthe L-shaped studs, such openings being disQ posed eXterior to thestuds.

The socket 3 is formed near one end with" a transverse opening 7 and inthe end ad-i jacent the opening 7 with an oblong recess 8 which jisincommunication with the open-' ing 7. The width of the, recess8flcorresponds to the width of the L-shaped studs and the length of therecess coincides with the distance betweenthe outer faces'of theL-shaped studs. When'the tool is properly applied to the socketthe studsfill the recess a 8 and preclude any movement between the tool andsocket. Dowels 9 project from the outer end of the socket and aredisposed a short distance from the'ends of the recess 8.

The dowels 9 are adapted to enter the 0penings 6 of the tool or pickhead, thereby materially strengthening and bracing the joint.

The connecting means between the tool and socket consist of a T-bolt 10and nut 11. The head 12 of the T-bolt is of a size to snugly fit betweenthe shanks i of the L- shaped studs and between the beaks 5 and theadjacent side of the tool. The width of the head 12 corresponds to thewidth of the studs. The threaded shank 13 of the T-bolt passes betweenthe beaks 5 and is adapted to project into the opening 7. It is notedthat the T-bolt may be placed in position from either side of the toolby slipping the head 12 and threaded shank 13 laterally between theparts 4 and 5 comprising the L-shaped studs. When the bolt is inposition the space between the parts 4 and 5 of the studs is completelyfilled, the side faces of the head 12 coming flush with the side facesof the studs.

The nut 11 occupies the transverse opening 7 and its outer end engagesunder the cross pieces of the socket spanning the outer end of theopening 7, thereby serving to hold the tool in place. The nut 11 isadapted to be turned in any manner and receives the threaded shank 13 ofthe connecting bolt. As shown, the nut 11 is formed in its sides with aplurality of'openings 14 to receive a pin or like appliance when it isrequired to apply force to turn the nut either when tightening orloosening the same.

In assembling the parts the connecting bolt is placed in position Withits head 12 between the shanks 4 and beneath the beaks 5 of the L-shapedstuds. The nut 11 is placed in the openings 7 of the socket after whichthe tool is placed in position with the threadedshank 13 of theconnecting bolt engaging the threaded opening of the nut 11. The nut isnow turned to draw the connecting bolt and L-shaped studs into therecess 8 and after the nut has been tightcried the tool will be securelyattached to the socket. It is noted that the spreading of the L-shapedlugs is prevented by reason of the same snugly fitting within the recess8. It is also observed that by reason of the L-shaped studs either oneor both may be easily replaced at a nominal cost in the event of eitherone becoming disabled or unfitted for further effective service. Shouldthe joint become loose after the tool has seen service the play may betaken up and the tool tightened by turning the nut 11 so as to draw thetool more closely to the socket. Having thus described the invention,What is claimed as new is 1. Means for connectinga tool to a handle, thesame consisting of a tool provided with apair of L-shaped studs arrangedwith their beaks projecting inward, a handle member having a transverseopening, and

a terminal recess intersecting with thetransverse opening and of a sizeto snugly receive the L-shaped studs, a connecting T- bolt adapted to beslipped laterally between the L-shaped studs from either side of thetool, the sides of the head of the bolt coming flush with the sides ofthe L-shaped studs and the threaded shank of the bolt passing betweenthe beaks or inner projections or" the studs, and a nut disposed in thetransverse opening of the handle member and receiving the threaded shankof the connecting bolt.

2. Means for connecting a tool to, a handle, the same comprising a toolhaving a pair of L-shaped studs with the beaks fac- 111g inward, saidtool havingopenings exterior to the studs and upon the same sidetherewith, a handle member having a trans verse opening, and an oblongterminal re'-' In testimony whereof I aflix my signature in presenceoftwo witnesses.
